Eddy current: Learn the eddy current definition

Learn the eddy current definition with formula, diagram, and examples. Understand how eddy currents work, where they’re used, and how to reduce eddy current loss in electrical systems. What is Eddy Current or What is Eddy Current's Principle? Eddy current is a current , which is circulate in conductors. In electromagnetism, an eddy current (also called Foucault's current ) is a loop of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. They can be induced within nearby stationary conductors by a time-varying magnetic field created by an AC electromagnet ... The ‘statically’ induced EMF and currents When there is no relative spatial motion or movement between the magnetic field and the medium, both being ‘stationary’ in space, but the former is changing with time, for example that produced by an alternating current as in Fig.1.2(b), the induced EMF follows directly from the second law of Faraday. This can mathematically be expressed by dØ e = (1.3) dt where Ø is the time-varying magnetic field to which the medium is exposed. The above ...
